1.Misfires: A flashing check engine light often corresponds with multiple cylinder misfires. Misfiring refers to the incomplete combustion of fuel in the cylinders, causing irregular engine operation.
2.Faulty Ignition: Flashing check engine light may indicate issues related to the ignition system, such as faulty spark plugs or ignition coils.
4.Catalytic Converter Issues: A flashing check engine light can also be a signal of a failing catalytic converter. This device is part of the exhaust system and controls harmful emissions.
5.Engine Coolant Temperature: If your engine is overheating or the engine coolant temperature sensor is malfunctioning, the check engine light may start flashing.
6.Throttle Position Sensor: A faulty throttle position sensor can also cause the check engine light to flash. This sensor provides the Engine Control Unit(ECU) with information about the throttle valve position.
7.Vacuum Leak: A significant vacuum can trigger a flashing check engine light. If there's a leak, the engine's air-fuel mixture is altered, leading to combustion problems.
8.Faulty Oxygen Sensor: If the oxygen sensor, responsible for monitoring oxygen levels in the exhaust, is malfunctioning, the check engine light may flash.
9.Transmission Problems: In automatic transmission Hyundai models, a flashing check engine light could be a sign of transmission issues, like low transmission fluid or a failing transmission control module.
It's essential to address a flashing check engine light as soon as possible. You can take your Hyundai to a trusted mechanic or an authorized Hyundai dealership to diagnose the underlying issue and ensure the proper repair is done.
